生理休眠

金莲花种子存在生理休眠现象，采用4周以上冷湿处理或不同浓度GA3处理可以打破休眠，GA3的最适浓度为500μg/g。

The physiological dormancy of Trollius chinensis seeds is proved in this article and it can be broken down by using moist-cold treatment over four weeks or GA3 treatment with different concentrations .

12d后（8月20日），观测到桑树和杨树芽已经开始进入生理休眠。

The bud physiological dormancy of mulberry and poplar initiated 12 days after the Ca 2 + influx was observed ( August 20 ) .

在生产上也可以采用提早采收的方法，避免种子进入生理休眠过程。

Early harvest also can be taken to avoid dormant physiological processes in Agricultural production .

短梗五加种子休眠属于复杂的形态生理休眠类型，种胚必须经过形态后熟和生理后熟两个不同阶段。

Acanthopanax sessiliflorus seed dormancy belongs to the category of morphological and physiological complex dormancy . The embryo must go through two phases of morphological postripeness and physiological postripeness .

可以判定，大果木莲种子具有浅度简单型形态生理休眠，冷层积可以打破其休眠组成中的生理休眠。

So we can say that the seeds of Manglietia grandis have non-deep morphophysiological simple dormancy , and the cold stratification can break the physical dormancy component of there complex dormancies .

种皮和胚乳的结构使种子吸水缓慢；种子成熟后，又经过了一个生理休眠过程，使种子进入休眠状态；种子中含有萌发抑制物质影响了种子的萌发。

The structure of seed coat and endosperm make the seed water absorption slowly . Seeds go into dormant after a physiological process which takes place after seed maturity . Inhibit germination material are contained in the seed , which affect the seeds germination .

生理性休眠体现在两方面：其一为种胚休眠，胚的活力低下。

Physiological dormancy is reflected in two aspects : One is embryo dormancy , embryo viability is low .
